IMPROVEMENT IN SNOW-GUARD$ FOR ROOFS.

Specification forming part of Letters Patent No. 193,509, dated August7, 1877; application filed April 14, 1877.

To all whom it may concern:

Be it known that I, PHILIP A. DUGAN, of Brooklyn, Kings county, NewYork, have invented, made, and appliedto use Improvements in theConstruction of Snow-Guards for the Roofs of Buildings; and that thefollowing is a full, clear, and correct description of my invention,reference being had to the accompanying drawings, making part of thisspecification, and to the letters of reference marked thereon, inwhich-- Figure l is an end view of the roof of a building to which mysnow-guard has been applied. Fig. 2 is a front view of the same.

In the drawings like parts of the invention are designated by the sameletters of reference.

The nature of the present invention consists in improvements onthe'patent granted to me March 13, 1877, No. 188,287, for improvementsin the construction of snowguards for houses or dwellings provided withpeaked or slanting roofs.

The object of the invention is to prevent the fall of snow or ice inlarge quantities from the roof upon which it has lodged or been formed,which is of frequent occurrence where snow-guards are not employed,endangering life and destroying property to a certain extent.

To enable others skilled in the arts to make and use my invention, 1will describe the construction and operation of the same.

A shows the peaked or slanting roof of a house or building to which myinvention has been applied. B shows what 1 term the slate or shingle,composed of iron or any suitable material, for receiving thedouble-flanged support 0 for the guard. This iron plate or shingle'B issecured to the roof A, forming one of the courses of slate or shingles,and is provided with the support 0 for the snowguard welded to it; orthe slate and support may be cast or rolled in one piece.

The support 0 consists of a plate of metal folded or formed so that thefolded or formed portions form wings 0r sides 0, extending from and infront of the back portion of the plate,

and then secured to the iron slate or shingle by welding or otherwise.

The projecting sides or wings are provided with a series of openings,01, rising above and in line with each other for the introduction of asnow-guard, composed of a series of rods, D; or if the snow-guard is tobe composed of a board or plate of metal, the same is attached to theopenings 6 in the back portion of the supports 0.

The number of supports 0 and lengths of rods or board required willdepend entirely upon the length of roof to beprotected, the supportsbeing placed about six feet apart, or less, if required.

Such being the construction, it will be seen that the object of theinvention is fully accomplished, and that the fall of large bodies ofsnow or ice from the roof to which the snow-guard has been applied willbe prevented. Aside from this, the guard can be easily and cheaplyapplied to a roof, and, when not required, the rods or board of which itis formed can be easily removed.

Having now set forth my invention, what I claim as new is-- Thecombination of the iron slates or shingles B, provided with the supports0, having the openings 01 and e, and a snow-guard formed of a series ofrods, D, constructed and operating substantially as and for the purposeset forth.
